# Phase 01 Plan 01: conflict-inventory-and-decision-matrix Summary

**交付了可复现冲突证据链、文件级风险清单与 Titan 重叠决策矩阵，形成“旧视觉+新逻辑”执行输入。**

## Performance

- **Duration:** 16 min
- **Started:** 2026-04-07T12:30:24+08:00
- **Completed:** 2026-04-07T04:31:40Z
- **Tasks:** 3
- **Files modified:** 5

## Accomplishments
- 固化了 merge hotspot 与 Titan overlap 的 Git 命令级证据链。
- 生成机器可消费的 `conflict-inventory.csv`，并给出 P0/P1/P2 风险分级口径。
- 生成 `titan-decision-matrix.md`，为后续 Phase 2/3 给出 keep/replace/hybrid 决策与 L0/L1/L2 边界。

## Task Commits

1. **Task 1: 生成可复现证据链与原始热点集合** - `d4cffcde` (docs)
2. **Task 2: 产出可审计冲突清单（MERGE-01）** - `92905bbe` (docs)
3. **Task 3: 产出 Titan 重叠决策矩阵并绑定后续输入（MERGE-03）** - `7499a699` (docs)

## Files Created/Modified
- `.planning/phases/01-conflict-inventory-and-decision-matrix/audit-evidence.md` - merge 与 Titan overlap 证据链
- `.planning/phases/01-conflict-inventory-and-decision-matrix/conflict-inventory.csv` - 文件级冲突清单（机器可消费）
- `.planning/phases/01-conflict-inventory-and-decision-matrix/conflict-inventory.md` - 风险分级与分类口径说明
- `.planning/phases/01-conflict-inventory-and-decision-matrix/titan-decision-matrix.md` - keep/replace/hybrid 决策矩阵
- `.planning/phases/01-conflict-inventory-and-decision-matrix/01-SUMMARY.md` - 执行总结

## Decisions Made
- 以历史 merge 冲突提交作为 Phase 01 的主审计来源。
- Titan overlap 决策必须绑定可追溯证据，不接受无来源结论。
- 将后续执行输入显式映射到 Phase 2（逻辑）与 Phase 3（视觉）。

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
- 无功能性阻塞。仅有一次沙箱写 `.git/index.lock` 限制，提权后已正常提交。

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness
- Phase 2 可直接消费 `keep` 与 `hybrid` 的 L0/L1 项。
- Phase 3 可直接消费 `replace` 与 `hybrid` 的 L2 项。
- 无额外前置阻塞。
